:sPEGEFICATION forming part of Letters Patent N 0. 657,1 11, datedSeptember 4, 1900.

Application filed September 23, 1899. Serial No. 731,413. (No model.)

T0 (6 whom it may concern:

Be it known that I, Euennro K. HAYES, a citizen of the Jnited States,residing at Galva, in the county of Henry and State ofIllinois, haveinvented a certain new and useful Improvement in Swings, of which thefollowing is a specification.

My invention relates, primarily, to portable swings or swings whichafter being set up can be moved around or changed as to location in theyard or other place where set up without the necessity of taking theswing down. Swings of this class require to be strong and rigid towithstand the usage to which they are subjected, and they should also belight and compact in order to be easily and quickly handled.

The principal object of my invention is to construct a swing that willbe strong, rigid, and durable and at the same time symmetrical andlight, employing in the construction light material without sacrificingthe strength and rigidity of the parts.

The invention consists in the features, combinations, and details ofconstruction hereinafter described and claimed.

In the drawings illustrating my invention, Figure 1 is an elevation inperspective showing the swing set up; and Fig. 2 a top or plan view ofthe upper end of the supportingframe standards and the bridge or block,showing the latter partly broken away.

In constructing my invention and applying the same to a swing I make aframe of two standards or uprights A. Each standard or upright is madefrom a single piece of metal, preferably high-carbon steel, rolled orotherwise formed into shape to have a right-angle conformation incross-section, presenting a lateral or side flange or wing and atransverse or edge flange or wing when set up for use. Each standard hasside pieces or legs a and a top or cross piece a, formed by bending thesingle piece of material into a yoke or U shape. The legs of thestandards have an outward or transverse spread at the bottom and are tobe set inclined to each other and connected at their upper end by abridge or tie piece 13, preferably a block of wood, held in place bytie-bolts Z2. A cross-arm O is secured to each standard at the upper endthereof by bolts 0, and running from the end of each cross-piece is adiagonal support 0, secured to the side wings of the pieces or legs ofthe standards by bolts 0 and secured together at the crossing-point,which is the central vertical line between the standards, by a bolt 0The cross pieces or arms and the diagonal supports form the head fromwhich the swing-bars are suspended, and the construction of this headand the manner of attaching it to the standards is such that the pushand pull in swinging and the thrust of the movement of the swing isreceived and borne by the cross arms or pieces and the diagonalsupportsand transmitted uniformly to and carried by the supportingframe-pieces or standards, so that the weight of the occupants and themovements of the swing are uniformly and evenly borne and distributed onthe head and the supporting-frame, rendering it practically impossiblefor the swing to tip endwise in ordinary use. The framepieces orstandards are secured at their lower ends to side timbers or supports Dby bolts d, so as to have a lateral inclination by which, in connectionwith the transverse spread of the side pieces or legs and thehead-blocks, the standards brace each other both laterally andtransversely against strain in use. The suspension or swing bars E, twofor each side of the swing, are mounted or suspended by eyes or hooks eon a cross rod or bar 6 at the outer ends of the cross-arms (1, whichrod also secures together the outer ends of the cross and diagonal arms.The

platform I", composed of side rails f and crosspieces f, is pivotallyconnected to and between the lower ends of the suspension or swing barsE, and the transverse spread of the standards and timbers or supports Dis suflicient to leave a clear space between the standards and theplatform and seats for the swinging movements without danger to theoccupant of a seat. The seats G, one for each side of the swing, areeach formed with a seat portion g and a back g,- and the seat portion issupported between the swing-bars by pins or pivots 1'. Each seat has anarm or side bar g attached by a pin or pivot 72, to the bar of the swingand having at the rear end a slot h, by means of which and a suit ablebolt and thumb-nut on the back of the seat or other suitable adjustingdevice the in clination of the seat as a whole can be ad-' justed andthe seat locked in its adjusted position.

The standards or supports A can be made of exceedingly light material,having a rightangle formation, as such formation gives great strengthand rigidity thereto, one wing or flange supporting the other. The twostandards, made of right-angle material set at a lateral inclination toeach other and having a transverse spread, form a wide base bolted tothe timbers or supports at the bottom. The bridge or piece at the top orapex rests against and is braced by the angle portion of the standards,as well as bracing the standards. The framework thus provided isexceedingly light in construction and at the same time has greatstrength and rigidity, owing to the inclined bracing formation bothlaterally and transversely and the bridgingsupport at the top, whichdispenses with other bracing than that had by the set of the standardsand the bridge at the top.

The head formed of the cross-pieces and 2 5 diagonal supports secured tothe frame-pieces or standards enables light material to be used for thehead, and by the arrangement of the cross arms or pieces and thediagonal supports a head-bearing of great rigidity and 0 strength isprovided, and the head is so constructed and secured in place to theside wings of the standards that the push and pull and the thrust fromthe movements of the swing are carried equally and uniformly, so that nostrain will be had on one portion more than on another.

By my invention a light, compact, and simple frame is provided, whichwill be found exceedingly substantial and Very durable and 4.0 stronginuse. A head is furnished, by which the strain and thrust in use is noton one part more than on the other, and the swing as a whole isconstructed of light material, not heavy and cumbersome, and can beeasily and readily handled.

The construction preferred is one having the frame or standard piecesmade of a continuous piece; but it is evident such pieces could bedivided at the top portion centrally,

and rigidity would be had by the bridging block or piece, and while theconstruction and arrangement are more specially designed for portableswings it is evident that they are adapted for and can be used forswings which are anchored or set permanently in a fixed position andattain the same results of strength and rigidity and a uniform and equaldistribution of the push and pull and strain.

The parts are fitted accurately, so that they can be easily put togetherat the place for use without employment of skilled labor, as all that isrequired is to set up and bolt the standards to the lower timbers orsupports and bolt the block or bridge piece at the upper end and attachthe cross-pieces and diagonal supports by bolting the same to the sidewings of the standard or frame pieces, suspending the swing-bars fromtheir rods and attaching the platform and seats in place between theswing-bars, which sets up the swing as a whole ready for use.

WVhat I regard as new, and desire to secure by Letters Patent, is-

1. In aswing, the combination of two standards, each having a body ofright-angle shape in cross-section bentinto a yoke or U form to haveside pieces or legs and a cross-piece or top, a bridge for the top ofthe standards, and a base for the bottom of the standards for the bridgeand base to set and hold the standards at an inclination, substantiallyas described.

2. In a swing, the combination of two standards, each having a body ofright-angle shape in cross-section bent into a yoke or U form to haveside pieces or legs and a cross-piece or top, a bridge for the top ofthe standards, a base for the bottom of the standards, and a headsupported at the upper end of the standards, substantially as described.

3. In a swing, the combination oftwostandards, each having a body ofright-angle shape in cross-section bent into a yoke or U form to haveside pieces or legs and a cross-piece or top, a transverse bridge forthe top of the standards, a base for the bottom of the standards, a headsupported at the upper end of the standards with its ends projectedbeyond the standards, and a swing-frame carried by the head,substantially as described.

4. In aswing, the combination of two standards, each havinga body ofright-angle shape in cross-section bent into a yoke or U form to haveside pieces or legs and a cross-piece or top, a bridge for the top ofthe standards, a base for the bottom of the standards, and cross-armsand diagonal supports secured to the standards at the upper end andforming a head for the swing-frame, substantially as described.

5. In aswing, the combination of two standards or supports set at aninclination and transversely bridged at the top, and a head secured tothe upper part of the standards or supports and consisting of cross-armsprojected at each end beyond the standards or supports and diagonalsupports extending from the ends of the cross-arms and across each otherand attached to the standards, substantially as described.
